Re: Problem with JSON Result and Form Submit
Ok, so the Dojo script needs to pass some data to the action, and that data is the one that comes from the first request right? musachy On Mon, Feb 9, 2009 at 2:54 PM, Christer Gjerstad christer.gjers...@gmail.com wrote: Almost.

Re: Problem with JSON Result and Form Submit
There are a lots of different ways of doing that. What I would do is:
1. add a field for the first action wit getters and setters for the params
2. in the jsp do something like:
script
var param1 = s:property value=''param1' escapeJavaScript='true'/;
var param2 = s:property value=''param2' escapeJavaScript='true'/;
/script
3. Call the second action passing the params to Dojo like:
{ 'param1': param1, 'param2' : param2}
Dojo accepts a map that it serializes into a query string (if it is
GET request). I forgot the dojo method signatures, google it up :).
This way you can avoid building the query string yourself, which is
always error prone.

So my question is; is that the way to do it? With the Dojo script that is,
passing the data into the action? Will not the params interceptor handle
this?
What I've done so far is to make another action class implementing the
ParameterAware interface so that I will get the incoming parameters. I then
create and return a querystring and get this from the value stack in the
page containing the Dojo script. I can then (hopefully) pass the information
retrieved into the action returning the JSON result. This I will do with
dojo.xhrPost and set the optional postData. Not solved this at the moment,
but working on it.
Seems like my solution is not that trivial so I would appreciate any help in
this matter! :-)

Hey
Re: Problem with JSON Result and Form Submit
I forgot to say, escapeJavaScript is available on 2.1 only. If you are
using 2.0, there is a similar method (actually the original one) in
commons lang StringEscapeUtils.
